1.7 Brief description
The actuator-sensor interface (AS-i) has established itself as a system for networking
primarily binary sensors and actuators at the lowest level of the automation hierarchy.
The high number of installed systems, the ease of use and the reliable operating
behaviour also make the AS-i interesting in the area of machine safety.
The safe AS-i system is intended for safety applications up to Category 4 in
accordance with EN 954-1. Mixed operation of standard components and safe com-
ponents is possible.
Notice!
A brief description of the safe AS-i transmission can be found in Chapter 12 at the end
of this operating manual.
The AS-i safety monitor monitors within an AS-i system the safe slaves which have
been assigned according to the configuration specified by the user with the configura-
tion software. Depending on the device model, up to two dependent or independent
OSSDs, each with external device monitoring circuit, are available. In the event of a
stop request or a defect, the AS-i safety monitor safely switches off the system in
protective operation mode with a maximum reaction time of 40ms.
Fig. 1.7-1: Safe and standard components in an AS-i network
Multiple AS-i safety monitors can be used within an AS-i system. In this way, a safe
slave can be monitored by multiple AS-i safety monitors.

2 Safety Notices
2.1 Safety standard
The AS-i safety monitor has been designed, manufactured, tested and presented for
prototype design testing in accordance with the safety standards applicable at the time
of testing. The technical safety requirements acc. to Category 4 as per EN 954-1 and
SIL 3 as per IEC 61508 are fulfilled for all devices.
Notice!
A detailed list of failure probability values (PFD values) can be found in Chapter 3.2.
Following a risk analysis, you may use the AS-i safety monitor in accordance with its
Safety Category (4) as a disconnecting protective device for securing danger areas.
2.2 Intended use
2.2.1 Application requirements
The AS-i safety monitor has been designed as a disconnecting protective device for
securing danger areas on power-driven working materials.
Attention!
The protection of personnel and the device cannot be guaranteed if the device is
operated in a manner not corresponding to its intended use.
Attention!
Access and changes to the device, except where expressly described in this operating
manual, are not authorised.
2.2.2 Residual risks (EN 292-1)
The wiring suggestions shown in this manual have been tested with utmost care. The
relevant standards and regulations are adhered to when the shown components and
appropriate wiring are used. Residual risks remain when:
• the suggested wiring concept is not adhered to and, as a result, the connected
safety-relevant components or protective devices are not or are inadequately
integrated into the safety circuit.
• relevant safety regulations specified for the operation, adjustment and mainte-
nance of the machine are not adhered to by the operator. Here, the inspection and
maintenance intervals for the machine should be strictly adhered to.
2.2.3 Areas of application
When used as intended, the AS-i safety monitor allows the operation of sensor-
controlled systems for the protection of persons and other protective components up to
and including Category 4 acc. to EN 954-1.
The safety monitor also performs the mandatory emergency shutdown function for all
non-hand-operated machines (Stop Category 0 or 1), the dynamic monitoring of the
restart function and the contactor control function.

74 ASM1, ASM1E
DEUTSCH ENGLISH FRANÇAIS ITALIANO ESPAÑOL NEDERLANDS
Examples for the use of the AS-i safety monitor:
The safety monitor is used commercially in machines and systems in which the
standard AS-i bus functions as the local bus. Thus, by using the safety monitor as a
bus subscriber, existing AS-i bus configurations can be expanded easily and safety
elements with corresponding "AS-i safety at work" interface easily integrated. If a safety
component does not have an "AS-i safety at work" interface, a so-called coupling
module can be used to make the connection. Existing AS-i master and AS-i power
supply units can continue to be used.
There are no branch-specific restrictions. Several of the primary areas of application
are listed here:
• Machine tools
• Expanded machining machines with multiple control elements and safety sensors
for wood and metal applications
• Printing and paper processing machines, cutting machines
• Packaging machines, single and as part of a system
• Food processing equipment
• Piece and bulk material transport systems
• Machinery in the rubber and plastics industry
• Assembly machines and manipulators

four safety monitors without address.
If fewer than 31 standard addresses are used, an additional
monitor can be installed for each standard address that is not
used. If additional subscribers are installed without address
(e.g. earth-fault monitoring modules), the number of installa-
ble safety monitors is reduced accordingly. If repeaters are

which is contained either in a protective housing or a switching cabinet and the monitor
can be accessed only by trained personnel. Nevertheless, we recommend that before
the user inserts the parameterisation cable into the safety monitor he perform a
discharge (earthing) at a suitable location.
3.2 Consideration of failure probability according to IEC 61508
To allow calculation of failure probability for the entire system, the AS-i safety monitor
returns a component which depends on the maximum uninterrupted switch-on time of
the output circuit(s).
This results in the following table:
Table 3.2-1: Failure probability depending on switch-on time
The switch-on time describes the period of time until the safety function was requested,
or the maximum period of time between two executed safety checks. During this check,
safe shutdown is tested by actuating every safe sensor.
The total operating time describes the safety system's service life from commissioning
to disassembly; it is used as the basis for calculating the failure probability.
Together with the failure probabilities of the other components used in the safety
system (e.g. AS-interface slaves) it is then possible to determine the overall failure
probability. The resulting value can be used for categorising the safety system under
the respective safety level in accordance with IEC 61508.
Switch-on time Total operating time PFD
3 months 10 years ≤4 x 10-5
6 months 10 years ≤6 x 10-5
12 months 10 years ≤9 x 10-5

4 Mounting
4.1 Mounting in the switching cabinet
The AS-i safety monitor is mounted on 35mm standard rails acc. to DIN EN 50022 in
the switching cabinet.
Attention!
The housing of the AS-i safety monitor is not suitable for open wall mounting. Provide a
protective housing in all cases when the device is not mounted in the switching cabinet.
Fig. 4.1-1: Mounting
To mount, position the device on the bottom edge of the standard rail and then snap it
onto the upper edge.

DEUTSCHENGLISHFRANÇAISITALIANOESPAÑOLNEDERLANDS
Notice!
When drilling above the device, cover the AS-i safety monitor. No particles, no metal
shavings in particular, should be allowed to penetrate into the housing through
ventilation openings as they may cause a short-circuit.
Mounting accessories
As the AS-i safety monitor is a safety component, it is possible to protect the device
from unauthorised access by sealing the CONFIG configuration interface and the
Service button. Included in the delivery contents for the device is a transparent cover
with safety hook through which you can pass a lead sealing wire or thread when the
device is in its mounted state (siehe Bild 4.1-2). You must break the safety hook off the
cover before using.
Fig. 4.1-2: Mounting accessories for sealing the device
Notice!
The transparent cover with safety hook should always be used as they provide good
protection against electrostatic discharges (ESD) and the penetration of foreign bodies
into the CONFIG socket of the AS-i safety-monitor configuration interface.
The sealing wire is not included in the delivery contents.
